id0112c3800400

1.  Measure the coolant temperature and specific gravity with a thermometer and a hydrometer.

Caution

•  The engine has aluminum parts that can be damaged by alcohol or methanol antifreeze. Do not use alcohol or methanol in the cooling system. Use only ethylene-glycol-based coolant.

•  Use only soft (demineralized) water in the coolant mixture. Water that contains minerals will reduce the coolant"s effectiveness.

Note

•  If the “FL22” mark is shown on or near the cooling system cap, use FL22 type engine coolant.

•  FL22 type engine coolant is shipped as a diluted solution (55% coolant, 45% water). Use the solution as is when replacing coolant.
